UNITED STATES MIKE KOSCHO, OF TRENTON, NEW JERSEY.

PADLOCK.

Application filed July 26, 1923.

To all whom it may concern: i

Be it known that I, MIKE Kosoi-ro, a citizen of Czechoslovakia, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Padlocks, of which the following is a specification.

This invention relates to new and useful improvements in padlocks.

An important object of the invention is to provide a padlock of a suitable design for adapting the same to be used as a connecting means for end links of a section of chain or for eyes formed at'the ends of a section of wire cable.

A further object of the invention is to provide a padlock that may be secured to the staple portion of a hasplock for preventing the removal of the metal strap from said staple.

A still further object of the invention is to provide a padlock of the above mentioned type that is exceedingly simple in construction, strong, durable, and one that may be manufactured at a very nominal cost.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a front elevational view of the padlock embodying this invention,

Figure 2 is a side elevational view of Fig. 1,

Figure 3 is a front elevational view of the padlock with the cover plate removed, and taken upon line IIII TT of Fig. 4,

Figure i is a vertical sectional view taken upon lines TV TV of Fig. 3,

Figure 5 is a transverse sectional view taken upon line VV of Fig. 2,

Figure 6 is a detail perspective view of the sliding bolt employed, and

Figure 7 is a side elevational view of the key employed.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the body portion of the lock casing which is formed with an inverted V-shaped projecting portion 6 at its upper end. By inspecting F ig. 3, it will be seen that the body portion 5 of this lock casing is provided with a transversely extending integrally Serial No. 653,934.

formed partition 7 which is provided with a centrally positioned recess 8 of substantially V-shape. The inverted V-shaped projection 6 is also provided with a transversely extending integrally formed partition 9 that is provided with a centrally positioned recess 10. Positioned at one side of the lock casing and extending between the transverse partitions 7 and 9 is a longitudinally extending partition 11 that is provided with a circular aperture12. The upper inverted V-shaped end 6 of the casing is provided in its side walls with transversely alined apertures 13 that are adapted for receiving the inwardly projecting ends of the bail 14 which are permanently secured in place, in the manner illustrated in Fig. 3.

In Figs. 1 and 4, there is illustrated a cover plate 15 that conforms in outline with the lock casing and is adapted to be permanently connected thereto by means of the rivets 16. This cover plate 15 is provided with a transversely extending elongated opening 17 at its lower end that is adapted for alining with the compartment formed in the rectangularly-shaped body portion 5 of the lock casing by the bottom wall of the same and the transversely extending partition 7 7 By inspecting Figs. 4 and 5, it will be seen that this cover plate15 is provided with a longitudinally extending groove 18 that is utilized for a purpose to be described in detail at a later point. The rectangularly shaped body portion 5 of the lock casing is provided in one side wall with a key hole 19 that isemployed for allowing the insertion of the key 20 therein and is in transverse alinement with the circular aperture 12 formed in the partition 11. It will be seen that this key 20 may be inserted through the opening 19 and may be positioned with its extreme forward end occupying the circular aperture 12 for the purpose of supporting the same.

In Fig. 6, there is illustrated a bolt that is formed with a three-sided body portion 21 having a longitudinally extending cylindrically-shaped shank portion 22. The body portion 21 is provided with a recess 23 that projects inwardly from one longitudinal edge of the same. It will be seen that this bolt is positioned within the lock casing in such a manner that the body portion slidably rests in the V-shaped slot 8 formed in the partition 7 and with the cylindrically- 7 receiving a portion of the spiral spring-2a.

The operation of the padlock is as fol- -lows:

The beveled end 25 of the bolt will cause the latter to move upwardly against the tension of the spiral spring 2 1 when the end links of a chain or any other similar object is forced through the elongated slot 17 formed in the cover plate 15. After the said links have been forced inwardly beyond the bolt, the spiral spring 24 will cause the said bolt to return to its normal position for preventing the withdrawal of the said links. To withdraw the said links from the casing, the key 20 is inserted through the opening 19 with the forward end of the key positioned within the circular aperture 12 formed in the vertically extending partition 11. The key is next rotated so that the laterally proj ecting lug 2O engages the recess 23 formed in thebody portion 21 of the bolt. By continuing the rotation of the key 20, the said bolt is moved upwardly against the tension of .the spring 24 for causing the lower end i of the bolt to be moved out of alineinent with the elongated slot 17. The links of the chain may then be withdrawn from the lock.

It is to be understood that the form of this invention herewith shown and described is to betaken as the preferred example of the same, and that various changes in the shape,

ing recesses formed therein, a cover plate having a transversely extending slot secured to said casing, a bolt slidably positioned within the recesses formed in said partitions and retained therein by said cover plate, a recess formed in one side of said bolt, a spring element for normally retaining the lower end of said bolt in a position to obstruct a portion of said slot, and a key having a laterally projecting lug adapted for engaging the recess formed in said bolt. for moving the latter out of alinement with said opening.

2. In a padlock of the class described, a casing having one open side and a key hole, a pair of spaced partitions within, said casing each having a width equal to that of the casing, said partitions having recesses out in their longitudinal outer'edges, a cover plate closing the open side of said casing, a bolt slidabl'y positioned in the recesses formed in said partitions and having its outer face flush with the outer edges of said partitions, said cover plate having a recess formed in its inner face concentric with the recess formed in one partition, a spring encircling a portion of said bolt and projecting into the recess formed in said cover plate, and a key adapted to be inserted through said key hole for engaging said bolt to move it against the action of said spring.

In testimony whereof I allix my signature.

MIKE KOSCHO.
